Manuscript Summary: This incomplete liturgical psalter was made between 1335 and 1350 in Naples. The unusual decorations are the work of the artist Christoforo Orimina. Because the manuscript contains three different coats of arms, the original owner (a member of the Angevin court in Naples) can not be definitively named. After changing hands many times during the 19th and 20th centuries, the manuscript was acquired in 1968 by the owner of the collection "Comites Latentes" ("Hidden Friends") held by the Bibliothèque de Genève.
